When you're pulling a heavy fifth wheel, gooseneck adapter, or bumper-pull trailer with a lifted or high-mount receiver truck, you need a ball mount that won't flinch. The B&W Hitches BMHD30212 delivers a genuine 16,000 lb gross trailer weight rating with a 4-inch drop and a full 6-inch shank designed for deep 2.5-inch receiver tubes. Forged and machined in the USA, this is the ball mount serious towers reach for when the load is real and the margin for error is zero.
B&W Hitches is best known for their fifth wheel and gooseneck hitch systems, but their ball mount lineup carries that same heavy-duty DNA. The BMHD30212 is part of B&W's Heavy Duty ball mount series, targeting towers who run full-size pickups with 2.5-inch receiver hitches and need significant drop to get a trailer tongue to the correct height.
The 6-inch shank length is specifically designed for receivers that sit deep in the hitch tube -- common on aftermarket receiver hitches, larger frame rails, and lifted trucks. The 4-inch drop handles the height difference between a raised hitch receiver and a lower trailer coupler, keeping the trailer level for proper weight distribution and tongue load performance.
Rated for up to 16,000 lb gross trailer weight -- appropriate for heavy travel trailers, horse trailers, car haulers, and loaded utility trailers.
Drops the ball platform 4 inches below the receiver centerline, leveling the trailer on lifted trucks or high-mount receiver applications.
The longer shank fully engages deep receiver tubes common on heavy-duty aftermarket hitches and larger OEM hitch assemblies.
B&W manufactures their ball mounts in the USA using forged steel for high-strength, consistent grain structure that meets or exceeds SAE J684 standards.
The BMHD30212 is sized for 2.5-inch receiver hitches -- the larger receiver class typically found on heavy-duty 3/4-ton and 1-ton pickup trucks (Ford F-250/F-350, Chevy/GMC 2500/3500, Ram 2500/3500) and some heavy commercial vehicles. This is NOT a standard 2-inch receiver ball mount. Confirm your receiver tube opening before ordering.
Receiver Size Check: Measure the inside opening of your hitch receiver tube. A 2.5-inch receiver has a 2.5-inch square opening. Most half-ton trucks use a 2-inch receiver. HD trucks and aftermarket HD hitches commonly use 2.5-inch. Using a 2.5-inch ball mount in a 2-inch receiver is not safe and will not fit correctly.
Getting the right drop is critical for trailer safety and performance. A level trailer -- with the frame running parallel to the ground -- distributes tongue weight correctly and prevents sway. Measure from the ground to the center of your receiver tube opening, then measure from the ground to the bottom of your trailer coupler. The difference gives you the drop (or rise) you need.
The BMHD30212 ball mount ships as a shank and platform only -- the hitch ball is NOT included. You will need to source the appropriate hitch ball separately based on your trailer coupler size. Common ball sizes for this weight class include:
The ball platform on B&W Heavy Duty mounts is drilled and tapped to accept standard ball shank sizes. A 2-5/16-inch ball with a 1-inch shank diameter and standard thread pitch is typical for this class of mount.
B&W Hitch Quality: B&W Hitches has been manufacturing towing products in Humboldt, Kansas since 1987. Their ball mounts are cold-forged from alloy steel, heat treated, and black powder coated for corrosion resistance. The company's reputation is built on fifth wheel and gooseneck hitches -- products where failure is not an option -- and that same standard applies to their ball mount lineup.
The BMHD30212 is a natural fit for the following towing situations common to RV owners and heavy-haul drivers:
Maintenance Tip: Inspect the shank pin retainer and hitch pin hole for wear after every 5,000 miles of towing. Clean and re-grease the shank before each season. Check the ball nut torque before every trip -- 2-5/16-inch balls typically torque to 300 ft-lb. Replace the hitch pin and clip if any play or deformation is visible.
Related Products: Pair this ball mount with a B&W or equivalent 2-5/16-inch hitch ball (1-inch shank, grade 5 or better), a heavy-duty hitch pin and clip or receiver lock, and a ball mount level indicator for proper trailer setup. If you tow at or near the 16K limit regularly, consider a weight distribution system for trailers over 6,000 lb.
